Re: [beagleboard] Is cape manager obsolete? What about device tree overlays?

I see that if I edit */boot/uEnv.txt* and comment out: #enable_uboot_cape_universal=1 I can then access all sorts of gpio pins. But now I can't run config-pin on them since there is no pinmux entry in /sys/devices/platform/ocp. Is there a way to free up a few gpio pins to drive the LCD and keep

[beagleboard] DDR initialisation on PocketBeagle

Hi, I'm currently trying to modify the (custom) MLO of my bare metal application in order to work with the PocketBeagle. At the moment this MLO works fine with BBB. According to the (incredibly small) manual of the Octavo SoC I changed the initialisation of the DDR and EMIF registers - but

[beagleboard] Re: BBB pps0 assigned to serial4

I have discovered that gpsd was causing the PPS device to get created for /dev/ttyS4. I had to recompile gpsd to turn off PPS support and that solved that particular part of the problem. The issue I'm running into now is that when systemd goes to start chronyd, the kernel has not yet created

[beagleboard] config-pin errors

I am feeling like an idiot here — this used to work a few months back, but I haven’t touched it in a while, and have done some system updates in the meanwhile. I can’t seem to get config-pin to do anything useful for me: debian@beaglebone:~$ sudo config-pin P9-23 lo [sudo] password for debian:

Hi Jason, Thanks for your information. I think we will use the U-Boot overlay method as you suggest. I was comparing the table (https://github.com/beagleboard/beaglebone-black/wiki/System-Reference-Manual#825-pin-usage. ) with the other sources. Regards Andrew From: Jason Kridner

Unfortunately, that's the command that gives me the error message. Someone else has control of those gpio's and I can unexport them, even as root. --Mark On Wednesday, November 29, 2017 at 9:34:35 AM UTC-5, William Hermans wrote: > > > > On Wed, Nov 29, 2017 at 7:27 AM, Mark A. Yoder
